text: You may simply be too soon.  Usually 22 to 30 months is considered the "standard" age.  With Our first daughter, we tried to "push it", and it turned into a horrible, long drawn out mess.  On the flip side, we didn't force the issue with our second daughter.  Then a few days before Preschool, we realized she hadn't yet learned.
  
  Our oldest said "No Problem Mommy." She explained it all to her sister, and she was potty-trained in a day.  So, when your child is ready, it will be a lot easier.  What you are doing now is fine, so that she can get used to it, but my advice is be patient.  She will learn when she is ready.
